As you and John eventually fall into the saferoom after a long run away from the usual sins- Carnation, Slugfish and Dozer if you were correct- you two took a well needed break. Within this time, you two cleaned up and got some sleep.
But, unbeknownst to you, while you were asleep. Genesis gave cards to John, wanting him to choose a new modifier. John had to pick something to protect you, after all. Something to keep you close to him, and easy to stay out of harm's way.
So, he picked the Marketable modifier, to make you around 4 inches tall.
As you wake up in the next 'morning' (there really were no mornings here, you just knew thanks to your mental clock), you find yourself... on a person's chest. Except you were bitty. John was watching over you like a careful papa bird.
"How was the nap, little one?" John asked, genuinely concerned for your wellbeing.
